The V2X drive test module sends out the data that acquire through the mode of DSRC or LTE-V, and the vehicle that is equipped with V2X equipment receives this message to send to the high in the clouds through cellular mobile communication, the high in the clouds gives road information board again.

Specifically, the drive test lidar module is a single-line or multi-line lidar and is used for supplying power to each module.

Specifically, the V2X drive test module is installed around the drive test laser radar and connected with the industrial personal computer, the roadside laser radar module is installed on two sides of a road and/or above the road and connected with the industrial personal computer, and the industrial personal computer module is installed around the drive test laser radar. The mounting position of the road information board is 0-10 m away from the two sides of the road, 3.5-6 m in height and/or in the middle of the road, the height is higher than the height limit, and the road information board is suitable for known mounting in all industries. The road measurement laser radar is arranged at a known optimal position to avoid shielding, and the distance between the road and the laser radar is 0-10 m, the height is 3.5-6 m and/or the middle of the road, and the height is higher than a limit height. The V2X road test equipment is arranged 3-5 meters away from the road surface, is not shielded on the basis of the road test laser radar, and is 0-5 meters away from the road test laser radar.

The beneficial effects of the utility model reside in that solved still can effectively discern road conditions under night and the extreme environment, and through DSRC mode or LTE-V's mode and through two kinds of network distribution of honeycomb mobile communication come out make do not adorn V2X equipment and the vehicle that is equipped with V2X equipment can all acquire the place ahead road conditions.
